Except he did. He put them on entirely different pages. Luffy, Jinbe, and Zoro were portrayed together. Sanji was portrayed with the rest of the crew. That matters.
You do realize that you’re saying that Sanji’s first fight in the New World, because this is his first full on fight in the New World, is going to be against a YC2 with literally no progression towards that level, right?
It doesn’t make sense, especially if you consider that he doesn’t need to at the moment, because the next few enemies are going to be more Yonko commanders, so he has time to build up to that level.
Also, the ambiguity of the end of the fight with Page One is purposeful to me.
